CLOTHES-WASHING MACHINE.

Specification of Letters Patent.

Patented (ict, gli., Militia.,

Application filed September 3, 1915. Serial No. 48,792.

To all whom it may concern Be it known that i, GEORGE WILLIAM GREEN,subject of the King of Great Britain and ireland, residing at Bobin, NewSouth Wales, Australia, have invented new and useful improvements inClothes-Vashing Machines, of which the following is a specification.

rihis invention relates to manually operated clothes washing machinesfor domestic use, and particularly refers to that type of such machinesin which the goods to be washed are placed with water and detergentsubstances in a rectangular box mounted on rockers and agitated thereinby rocking said box.

in the type of machines above referred to now in use, certain means havebeen pro` vided for applying a rubbing motion to the goods during therocking process, but these means have proved to be of limitedeffectiveness only. Machines of the rocker type have also provedobjectionable in that when operated they tend to move about from placeto place on the floor of a laundry while being rocked and are thereforefound inconvenient in use.

My present invention aims primarily to apply to the goods in the washingprocess a certain definite movement in the box chamber and to apply tothe water in which they are being washed a certain definite surgingmotion, whereby the goods will be caused to change position in the boxand to suffer adequate rubbing, while the water will be caused to swillthrough and about them in a regular manner, thereby facilitating andquickening the washing operation, and it furthermore aims to providemeans whereby such machines may be retained in a certain position on alaundry floor thereby to obviate the inconvenience caused by theirmovement from place to place thereon during the rocking process.

Certain regard must be paid to the proportions of the measurements of.such machines in order that the natural period of oscillation willsynchronize with the surging movement of the water in the box chamberduring the rocking process. in an e'ectively proportioned machine asshown in the accompanying drawings, the depth and the length of the boxchamber in relation to its height above the rockers and in relation tothe camber of the rockers is such as to obtain a balance which minimizesthe power required to effect the rocking and insures effective and rapidwashing. The height in this case to the top of the box chamber is threefeet six inches, the length of the box chamber is three feet six inchesand the rockers are struck to a four feet radius. It is obvious howeverthat for a difference in the length of the box or a difference in theheight of the machine a proportionate alteration needs to be made in theradius on which the rockers are curved.

The rectangular box is fitted with a stout deflecting cleat of V-sectionon one side of it, while its other side is fitted with two suchdeflecting cleats symmetrically disposed in relation to the length ofthe side, while on the bottom of the box two similar deflecting cleatsare fitted arranged angularlv between the vertical defiecting cleatsbefore mentioned which are fitted to the sides of the box.

As contradistinguished from machines of similar type in which adifferent arrange ment or a larger number of cleats are fitted, thedisposition of the deflector cleats according to the present inventioninsures rapid change of position of the goods in the box during thewashing process, while the water is caused to surge rapidly to and froin a curve approximating to the shape of the iigure 8. rlhe meansprovided for preventing movement of the machine about the fioor duringuse consists in articulated arms fitted to the rockers at either end ofeach of them, one end of each such arm is pivotally attached to therocker and the other pivotally attached to a lug adapted to be fixed tothe floor of the laundry or fixed upon a platform.

rlhe top of the box is constructed with a surrounding coaming and isfitted with a drop-in lid with dog bar fastening. The discharge vent inthe bottom of the box is fitted with a hose and cock to facilitateemptying used washing water into a sump drain or portable vessel.

ln the accompanying drawings, Figure 1 is a perspective external view ofthe machine, and Fig. 2 is a similar view drawn in phantom to illustratethe arrangement of the deflecting cleats.

A designates the rockers, B the legs by means of which the rectangularbox C is mounted on said rockers, D the vertical deflecting cleat at oneside of the box, E two vertical deflecting cleats at the other side ofthe box, F two angularly disposed dellecting cleats on the bottom of thebox, G lid, H dog bair vformed of a slightly cambered stili lath,

one end of which is engaged in a notch in the cross member J, its otherend being engageable by a turn button K.

L is a coaming surrounding the top of the box.

. M is the waste pipe connected to a vent at the foot of the box, and Na cock on said waste pipe.

O and P are links articulated together at Q, pivotally attached to therockers near the ends thereof at R and pivotally attached at S to lugs Twhich lare adapted to be fastened down toa floor or to a carryingplatform.

The machine is operated, when charged with water, detergents, and thegoods to be treated, by applying to it a regular rocking movement formore or less time depending upon the condition of the goods. This move-Copies of this patent may be obtained fof nve cents each, by addressingthe nient is applied by the operator manually. the handpiece U acrossthe ends of the box forming a convenient means for applying the motion.

What l claim as my invention and desire to secure by Letters Patent is Aclothes washing machine of the rocker box type having two bottomdeflecting cleats arranged at an angle and obliqucly end to end in thebox and three vertically disposed delecting cleats on the sides of thebox in staggered relationship with two of said vertical oleats on oneside of the box and one on the other.

In testimony whereof I have signed my name to this specification in thepresence oil two subscribing witnesses.
